A CAPTCHA is a type of test used to protects website services against use by automated programs that might abuse or otherwise take advantage of the service. The idea is to have a simple question that is easy for a human to answer, but difficult for a computer program. The standard technique is to ask users to type in text shown in an image. Typical applications include protecting registration and comment forms.

Comment spam is a phenomenon of guestbooks and blogs and other online feedback tools being filled with "comments" that are really just link droppings placed with the purpose of being noticed by Google.

News and advice related to referrer spam and how to stop it.

Some websites collect data on visitors to their website. One bit of gathered data is the address of the website the visitors came from. This address can be faked, and referrer logs are increasingly being filled with "visits" from sites with innocent-looking addresses - but they are actually porn or herbal medicine or other spammy sites. The spam might not be noticed unless they are in the top 10 or top 20 visitors of a site -- so they relentlessly visit a site in order to push their address to the top of the analysis chart. This is referrer spamming.
